DRAWING AND SUSPENDING CURTAINS.

Application filed February 10, 1827, Serial No. 167,136, and in Great Britain February 13, 1926.

The present invention relates to improvements in or relating to drawing and, suspending curtains wherein the curtain is carried by runners of the kind comprising a roller adapted to run on a strip-like race, and a frame on which the roller is pivoted, and from which the curtain is suspended.

The present invention aims among other things to reduce frictional reaction between the parts, notably between the roller and the race, and the roller and its frame: also to reduce tendency of the runners to bind on the race or jam one another: also to promote steady and true running of the runners along the race; and also to provide a runner which can be profitably manufactured, and which will run in series so steadily and truly and comparatively frictionless along the race with little or no tendency to interlock with or am among each other or bind on the race that the lastingness in a dependably freely operating condition of curtain drawing and suspending means of the kind herein referred to is much promoted.

According to the present invention there is provided a curtain runner having a flat strip-like race like an edge rail or track; running on this edge rail or track is a plurality. of grooved rollers having thick,

dome-shaped flanges, which extend outwardly on either side beyond the track. The contacting parts of the rollers and the track are such that the roller contacts with points only on angular edges of the track,

which the thickened dome-shaped flanges act as cooperating sto jamming of the ro lers when they are brought into close order.

In the hereinafter described embodiment a round grooved pulley is described and serves well, but a V-grooved pulley will also serve or, as a variant, the track face may be formed concave or V-grooved if desired.

The dome-shaped flanges as well as serving to prevent the rollers from jamming one another when brought into close formation along the race, further serve to provide a long axis for the roller which militates against wobbling and promotes true steady running of the runners.

Another features consists in so forming the frame of the runners for example of wire that from the upper end forming an axle portion which passes freely through members to prevent the roller and may be riveted to hold the roller thereon, a medial downwardly bent portion bends inwards towards the race but so as to clear the face of the pulley and to form a preferably comparatively long guide on the race to prevent undue canting of the runner when the curtain is pulled.

The invention is illustrated in the accompanying drawings, in which Fig. 1 is a front view of the general arrangement.

Fig. 2 a side elevation of one of the runners, and

Fig. 3 a front view thereof.

Fig. 4 is a side sectional elevation of a variant arrangement.

In the embodiment depicted in the drawings, the frame 1 of the runner is made up of a suitably bent piece of wire. The bent end 2 of the frame forms an axle for a grooved roller 3 and is riveted at 4 to hold the roller thereon.

The roller 3 is provided with a rounded groove 5 so that the grooved part of the roller only makes contact with the strip-like race 6 at the angular edges 7 8 of the track face 9. The groove may be V-shaped instead of rounded, or the desired effect may be realized by grooving the track face 9 as shown by 17, F ig. 4 in order that the grooved part of the roller shall contact only atthe edges of the track.

The end flanges 10, 11 of the rollers are thickened and their outer faces are backed away from the depending part of the frame 1, by the dome-shaped faces 12, 13, so that the roller and the depending part of the frame are kept from contact with one another. The thickened dome-shaped flanges also serve to keep the runners out of that overlapping relationship which tends to cause them to jam one another.

The vertical part of the wire frame 1 bends inwardly towards the race to form at 14 a preferably comparatively long guide so as to prevent undue canting of the runner when the curtain is pulled.

The lower end of the frame 1 forms a hook 15 which engages behind the race and retains the runner in position thereon. The hook may carry a ring or like 16 by which the curtain may be suspended.

What I claim is 1. Curtain suspending means comprising a track, a grooved roller having thick dome shaped flanges which extend outwardly well beyond the track on either side thereof, the groove in the'roller and the upper edge of the track being shaped so that they engage only at two laterally spaced points, a support having a horizontal portion extending through the roller and having a portion extending down alongside the track and engageable around the lower edge thereof the dome-shaped flanges preventing the rollers jamming when in close order.
